Quantitative risk influencing factors (RIFs) are proposed, using the Conjugate Bayesian update approach to analyze 945 collision accidents and incidents cases from the Jiangsu Segment of the Yangtze River over five years from 2012 to 2016. The accident probability is compared under a pairwise comparison mode in order to reflect the relative risk between accidental situations. The Bayesian update mode is constructed to quantitatively evaluate the relative importance of different RIFs. The riskiest segment of Jiangsu Waterways as well the main causations of collisions are identified based on the distributions of collision risk in the six segments of the waterways. The results can support managers to develop the most effective policies to mitigate the collision risk.

Patient blood management is the umbrella term for a suite of initiatives designed to optimise blood product usage, minimise transfusion needs, and ensure appropriate and evidence-based transfusion practices. In this review we summarise published economic evaluations of patient blood management to determine whether they represent good value for money. We identified 54 economic evaluations of patient blood management, the majority of which had positive cost-effectiveness conclusions.

The issue of obesity continues to reach new levels globally, affecting individuals across the age continuum. Obesity in pregnancy is associated with myriad comorbidities which may negatively impact the fetus, particularly dysfunctional labor and failure to progress ending in unplanned cesarean delivery. Neuraxial anesthesia represents the gold standard for cesarean delivery anesthesia and is increasingly beneficial for obese patients due to the risk of difficult airway.

Since 2015, reductions in maternal mortality have stalled globally. In some parts of the world, severe maternal morbidity and mortality have increased, and most cases are thought to be from preventable causes. This is further exacerbated by significant racial, ethnic, and geographic disparities in maternal health outcomes, particularly among countries with diverse populations.
